My husband and I try to travel carry on only . . . and still abide by the
carry on regulations. We're usually successful when leaving for an
adventure, but if we get too creative with purchases, have to send them
home.

We will take some of our clothing which is becoming worn, elastic starting
to give, etc so we can discard it along the way. Try to get items which go
together. You may have a blazer with a wild pattern, but have pants and
skirts in a solid which picks up a color in the jacket. Make sure
accessories are interchangeable also. You should be able to get by with
three shirts or tops, two skirts or pants, two dresses, or two more pants,
or shorts, two blazers and a vest, or three jackets, one ea of casual,
dressy, tennis shoes, depending on the situation. As long as your colors
work with each other, you should be able to make it.
